LIQUID TREATMENT coma Filed Nov. '14, 1930 spun Patented Get. 6, 1931 PATENT OFFICE a JOHN HENIGE; OF GHICAGQILLINOIS LIQUID TREATMENT COMB Application filed November 14, 1930. seriaiuo. 495,683.

The device of my invention relates to means for supplyingliquid, and particularly hot 011,5 to the roots of'the hair, and is an improvement over my prior Patent No; 1,661,-

- 287 jof March 6,1928,v T

It is common practice to employ mechanical meansfor supplying liquid te; thescalp, and

Q likewise common to providemeans for supply ng' fhot oil to the vscalp, but. the manner in which'this has" been accomplished in the past has'been very crude, impractical and lnefiic ent. This because of numerous struc- {tural' defects'inflthe apparatus which'I be lieveI haveeliminated ,inthe device herein '15 illustrated." J j The main object ina deviceof this charac-: ter to provide simple and eflicient means for directly supplying hot oil to the very meteor the hair. The device herein suppliesthe oil directly through the apertured teeth in a free and unobstructed manner. It has been found'impractical-to provide the usual form of'comb teeth with a fine enough discharge aperture therein,'the resultbeing 2 too great a flow of'oil.' The improved de vicetherefore, provides individual hollow teeth of uniformv diameter, apart only of said teeth having j 'discharge openings, the number of discharge openings provided heing variable to suit "individual requirements,

if desiredi In addition I may provide 'discharge openings on ;alternate sides of the teethinstead of all openings on one side, or twodischarge openings in a single tooth. I

also contemplate providing'the end teeth and some'intermediate teeth of solid, metal construction of the same cross section as the hollow teeth. Thus the danger of breakage a foreignmatter will not be likely to clog the discharge openings inthe teeth, but will be wiped 0a in passing through the hair; A

o-fthe, relatively fragile hollow teeth is considerably minimized. This is made/[possible the outer end terminating in a projection to which the handle is secured. Thus no threadmg or fitting of the inner chamber to the head is necessary, and in addition the placing of the inner chamber centrally within the head provides the greatest heat absorption efficiency. This for the reason that the heating chamber is only in contact with the oil, and the heatmust first be communicated to the oil before it can'escape. Thus it is unnecessary to first heat a largeamount of metal.

My inventionwill be more readily understood by reference to the accompanying drawings, in which:

' Fig. 1 is a side elevation of my improved liquid treatment comb i Fig. 2 is a longitudinal sectional view thereof, and a Fig. 3 is ahorizontal sectional view taken on the lines 83 of Fig. 2.

, By'reference to the drawings it will be seen that my comb comprises a hollow handle 10, having a recess at the outer end for the, reception of electrical connecting means 11. The upper end of the handle 10 is adapted to fit snugly over the projection 12 formed as a part of the. head'orliquid reservoir 18, and to contact the shoulders l llformed thereon.

Tlie head 13 is preferably molded in one no single piece and provides a rest 15, filling opening 16, having the cap 17, and the centrally disposed, internal," hollow chamber 18, closed at its inner end, and open at its outer end, and adapted to receive electrical heating means 19 operated by the wires 20 from the plug 11. i

On one side of the head, opposite to the rest 15 the head is reduced in cross section,

as best shown in Fig. SfThis portion 21 is 1 V providcd'with a plurality of spaced apertures 22 for the reception'of hollow tubing, having closed or iniperforate ends. A portion of the teeth QZiare provided with side discharge op ,enings 241 It is understood that the openings 24may be formed'cn .one'or both sides of the teeth. "It; has also beenfound desirable to form one opening on opposite sides of alter'nate rteeth,. so that the openings are in teeth not: having discharge openings.

. It will thus be seen that have provided a:
